Active Monitors overview

Active Monitors query network services installed on a device, then wait on the response. If a response is not received or if the response does not match what is expected, the service is considered down, and a state change occurs on the device.

If the query is returned with the expected response, the service is considered up. The following Active Monitor types are available in WhatsUp Gold:

• DNS Monitor
• NT Service Monitor
• Ping Monitor
• Active Script Monitor
• SNMP Monitor
• TCPIP Monitor
• Telnet Monitor
• WMI Monitor (WhatsUp Gold Premium)
• Microsoft® Exchange™ and Microsoft SQL Server Monitor (WhatsUp Gold Premium)

Note: There are several types of TCPIP Monitors that are configured using the same dialog.
